求助分页不正常
从查询页选择查询条件后,跳转到本页,可以查询到结果,下部三个文本框内的值也是对的,得到的where语句是where tgyc='事故不明' and qukuai_id=1and youtian_id=1 ,点击下一页后,查询结果就成了空,wwhere语句变成了where tgyc <> ''and tgyc is not null and youtian_id= 

<% syoutian=trim(request.form("fyoutian"))
  if syoutian="==请选择油田==" then
  s1youtian=""
else
s1youtian="and youtian_id="&syoutian
end if  
  squkuai=trim(request.form("fqukuai"))
  if squkuai="==请选择区块==" or squkuai="" then
  s1qukuai=""
else
s1qukuai=" and qukuai_id="&squkuai
end if  
  stgyc=trim(request.form("tgyc"))
  if stgyc="" then
if s1youtian="" then
s1tgyc=" where tgyc <> '' and tgyc is not null"
end if
else
  s1tgyc="where tgyc='"&stgyc&"'"
end if
